Americans fail math test on fuel consumption

Reuters reports on a novel concept — adopting a measure of consumption that people could easily understand for fuel:

When presented with a series of car choices in which fuel efficiency was defined in miles per gallon, the students could not easily identify the choice that would result in the greatest gains in fuel efficiency, he said.

People had a much easier time when fuel efficiency was expressed in gallons per 100 miles. In that case, a car that gets 18 miles per gallon uses 5.5 gallons of gas per 100 miles, and a car that gets 28 miles per gallon uses just 3.6 gallons per 100 miles. With gasoline prices over $4 a gallon, that’s a difference of about $8 per 100 miles.

“If we just turn everything around, you can see where are the large savings in gallons of gas,” Larrick said in a telephone interview. The idea is not new. Many other countries, especially in Europe, already use a standard that compares gas used per trip.

Uh-oh. Does he realize that comparing the US to Europe is likely to create discontent among those in America who refuse to acknowledge progress can happen anywhere else in the world?

To translate miles per gallon into gallons per 10,000, Larrick said people can simply divide 10,000 by miles per gallon. Cars with the highest miles per gallon are always the most fuel efficient, he said. It is when people are trying to replace a car that they may be misled.

That’s how he became interested in this problem.

“We were trying to decide whether to get rid of a minivan and go for a station wagon versus getting rid of a sedan and going for a really high-mileage hybrid car,” Larrick said.

“We realized in the end we were better off trading in the minivan and only gaining 10 miles per gallon then we would be trying to swap out the sedan for a highly efficient car.”

Excellent article. The fact that it highlights a real measure instead of searching for the most effective marketing campaign or the creation of feelings about better consumption…it’s practically un-American.

McCain Drilled on Oil Money

Ha ha ha. This is a funny (or perhaps sad, but I’ll go with funny for now) commentary on Senator McCain’s position on energy reform. The Wall Street Journal blog exposes a serious concern for voters:

As McCain was talking about his energy plans, a protester in the audience at Missouri State University yelled out that McCain had accepted a half million dollars this year from “big oil.”

“That’s more than any other senator!” he yelled. “How can you be trusted?”

After the event, McCain was asked in a news conference if that were true, though the questioner mistakenly quoted the protestor as saying McCain took in a half billion dollars.

“I don’t know what he’s talking about. So I can’t respond,” he said.

Indeed, McCain does lead all other senators, and all others who ran for president, in contributions from the oil and gas industry, according to the Center for Responsive Politics’ analysis of federal data in the 2007-08 election cycle. McCain collected $724,000 through May.

This is more than double the amount his competitor has collected. It is little surprise that the energy industry lobbies candidates and pays heavily for government protection. The problem is McCain claims to be ignorant of his relationship with oil, and yet is aggressively calling for expanded drilling. When it comes to security, pro-BigOil policies usually mean bad news for America, so I expect a candidate to take a stand on energy reform that puts oil in perspective. This news shows McCain could decide to undermine his own country for personal financial gain.

Updated to add (June 20, 2008), an article by US News has California Republican Governor explaining the issue nicely:

“We are in this situation because of our dependence on traditional petroleum-based oil,” Schwarzenegger said. “The direction our nation needs to go in, and where California is already headed, is toward greater innovation in new technologies and new fuel choices for consumers. That is the way we will ultimately reduce fuel costs and also protect our environment.”

Barack Obama, the presumptive Democratic presidential nominee, has also declared his opposition to lifting the moratorium on offshore drilling.

Kudos to Schwarzenegger for being so clear on this issue and advising how to manage the risks from a more balanced perspective.

Honda fuel cell…yawn

I know, I should be excited about fuel cells. The Governor of California says it is important, but I honestly do not see them playing any significant role for many decades to come. The AP has posted a story that includes the bad news with the good:

The biggest obstacles standing in the way of wider adoption of fuel cell vehicles are cost and the dearth of hydrogen fuel stations. For the Clarity’s release in California, Honda said it received 50,000 applications through its website but could only consider those living near stations in Torrance, Santa Monica and Irvine.

Initially, however, the Clarity will go only to a chosen few starting July and then launch in Japan this fall.

California Gov. Arnold Schwarzenegger has called for a statewide network of hydrogen stations, but progress has been slow.

No kidding. He might as well have called for statewide adoption of unicorns. Where are these expensive hydrogen stations going to come from? Big oil? Energy companies? Ha.

The state has also recently relaxed a mandate for the number of zero-emission cars it aims to have on roads. By 2014, automakers must now sell 7,500 electric and hydrogen fuel cell vehicles, a reduction of 70 percent.

Talk is cheap, obviously. Why reduce the pressure for demand? Hydrogen is a pipe dream since it requires a massive investment in infrastructure technology that does not even exist yet. Diesel, on the other hand, could achieve similar results with technology that is present today and does not require a change of heart for the oligopoly of big energy companies. Perhaps I should say oil-gopoly?

The US energy department paints a pessimistic picture for hydrogen fueling stations:

If hydrogen were priced to provide cost parity with conventional vehicles, most hydrogen infrastructure stakeholders could turn a profit in the long run, but break-even would not be achieved for many years.

Unconventional approaches are needed to improve capacity factors and reduce the capital cost of the hydrogen infrastructure, especially in the early years of infrastructure development.

Here is a real shocker, for example:

Utilizing existing excess hydrogen capacity can result in significant capital investment reductions in the early years. These cost reductions need to be examined on a regional basis, for example, in the Midwest, 50 percent of the population is within 100 miles of an existing hydrogen plant.

If you want the fuel, you will have to live in low-value industrial regions like those favored by giant chemical plants (e.g. ammonia). Sound like a good trade-off to you? Do you want to live next to an oil refinery to get petroleum into your car? No, of course not. Again, diesel needs only natural sources of oil such as plants, animals and minerals nearby. Imagine living near a forest, or restaurants, or a coast-line with algae, or even a desert with algae for that matter. I see the hydrogen generation/transportation problems many decades away from being solved, or presenting a suitable model.

Diesel wins Le Mans race for fifth straight year

The first year of the LMP1 class win was a wonderful story, the second year a “told you so”…the third year was “anyone still doubt the future of diesel“…and now the news is almost not news anymore. Diesel engines should be the future of mobile power-plant technology in 2010 the way PCs were the future of computing in the 1980s. USA Today reports that Audi continues to leave gasoline in its dust:

Audi and Peugeot completed a record of more than 3,200 miles around Circuit de la Sarthe in France, a trip which 55 cars began but only 20 finished. The lead Audi and Peugeot, both diesel-powered LMP1 prototypes, were never separated by more than a lap, thrilling a record 258,000 fans.

The top cars are diesel. Way to go Audi R10 TDI!

It is a 5.5 L (335.6 cu in) all-aluminium twin-turbo 90° V12 engine, with common rail direct fuel injection of more than 1600 bar (23,206 psi). Its output should be 485 kilowatts (650 hp) (regulated) and 1,100 N·m (811 ft·lbf) of torque, and its usable power band is between 3000 and 5000 rpm. Its benefits are a broad range of usable power, high torque and economy.

Two Garrett TR3076R turbochargers limited by the regulations to 2.94 bar (42.64 psi) absolute breathe through two 39.9 millimetres (1.57 in) intake air restrictors. It uses the latest Bosch Motronic (MS14) management, provided by Bosch Motorsport, 1600 bar piezo injectors, and makes a low noise for a race car. It can be difficult to hear the R10 on a track when other cars are present because of the much lower noise level.

Economy and silence in a super-power diesel race car! Amazing stuff. This is not your grandmother’s diesel.
